Description
Technical field
It the utility model is related to a kind of damper, more particularly to a kind of automobile Double-drum type shock absorber of high reliability.
Background technology
The main function of damper is concussion when suppressing to rebound after spring element shock-absorbing and impact from road surface.When
When being vibrated between vehicle frame and vehicle bridge and relative motion occurs, the piston inside damper is reciprocating in fluid, and fluid exists
Oil pressure effect is lower to be flowed back and forth by each valve, through hole and normal open hole, since valve produces damping force, Yi Jikong to fluid
Friction between wall and fluid forms damping force to vibration, so as to consume vibrational energy so that vibration decay, improves automobile
Riding comfort.
However, automobile is in severe driving cycle downward driving, traditional vehicle shock absorber its oil pressure during the work time
It can sharply increase, cause each part of internal piston more fragile.Meanwhile damping force is difficult to control needed for damper, damping force mistake
Greatly, then the comfort of automobile in flat road surface when driving can be influenced；Damping force deficiency, then can cause the phase of damper inner body
Mutually hit, so that automobile acutely shakes, do not reach effectiveness in vibration suppression.
Chinese patent CN105889393A discloses " damper and the vehicle with the damper ", which provides
A kind of damper that helical spring is provided between guide holder and piston, since rigidity of helical spring is smaller, easy frequent quilt
Limiting condition is compressed to, causes decrease or the forfeiture of spring, or even produce permanent deformation.The utility model employs three
The closed air bag spring of the different rubber of internal compressed gas pressure, three air bag springs are installed in parallel on the piston rod, due to gas
Capsule spring rate is raised and increased with compressed gas air pressure, then air bag is not easy to be compressed into limiting condition, can reach damper
More preferable bradyseism effect, reliable operation and service life are grown.
Utility model content
For the above problem of the prior art, the purpose of this utility model is that proposing a kind of automobile double of high reliability
Cylinder type damper, this damper can effectively slow down the trend that oil liquid pressure sharply increases, and damping force can be with automobile running working condition
Change and change, reach comparatively ideal damping effect, so as to improve the ride comfort and comfort of running car.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of automobile Double-drum type shock absorber of high reliability, including it is work cylinder barrel, piston rod, first piston, guide holder, slow
Punching pad, air bag spring group and second piston, the first piston are installed in parallel on the piston rod with the second piston,
The cushion pad and the air bag spring group are installed between the guide holder and the second piston.
Further, there is the axially extending bore being uniformly distributed along the circumference in the second piston, the second piston is sheathed on described
On piston rod and it is placed in above the first piston, the first piston and the work of the second piston are independent of each other.
Further, the air bag spring group is sheathed on the piston rod and is placed in above the second piston, described
Air bag spring group is made of the first air bag spring, the second air bag spring and the 3rd air bag spring, the first air bag spring, the second air bag
Spring and the 3rd air bag spring are installed in parallel, and cushion pad, the first air bag spring and the second air bag are provided with the first air bag spring
Cushion pad is mounted between spring and between the second air bag spring and the 3rd air bag spring；First air bag spring, the second gas
Capsule spring and the compressed gas air pressure in the 3rd air bag spring are incremented by successively from top to bottom, and the size of air bag is sequentially increased, and make to subtract
The effectiveness in vibration suppression of device during the work time of shaking is more gentle effective.
Further, when first air bag spring reaches maximum with the second air bag spring deflection, its edge will not
Contacted with the work cylinder barrel, when the 3rd air bag spring deformation is up to amount to maximum, its edge will not be by the second piston
On through hole completely enclose；The internal layer of each air bag spring is made of the rubber of air-tightness, and outer layer is made of oil resistant rubber.
Compared with prior art, the utility model beneficial effect is：
By setting three air pressures and the different air bag spring of size between piston and guide holder, when automobile is severe
Driving cycle downward driving when, due to the compression of air bag spring, air bag spring produces reverse elastic force to piston, can slow down
The trend that oil liquid pressure sharply increases, makes the damping effect of damper during the work time more gentle effective, so as to improve vapour
The ride comfort of car traveling.
By installing second piston between the 3rd air bag spring and first piston, in the extension stroke of damper, when
During the 3rd air bag spring compression, with the increase of deflection so that the axially extending bore in second piston is by the 3rd air bag bullet
The area that spring covers is increasing, and epicoele fluid passes through the axially extending bore of the 3rd air bag spring and second piston under pressure
The orifice restriction of formation, so as to produce a kind of additional damping force value.
Meanwhile by setting cushion pad between the first air bag spring upper end and each air bag spring so that each air bag
Spring being more uniformly stressed during being compressed, and a kind of guiding role can be played, reduce air bag spring and working
During friction between working cylinder barrel so that damper work is relatively reliable, extends the service life of damper.
